IMPROVEMENT IN STRAW-TWISTING MACHINES.

Specification forming part of Letters Patent No. 160,777, dated March16, 1875; application filed August 31, 1874.

Case. D.

specification, and to the letters and figures of reference markedthereon.

Figure 1 of the drawing is a representation of a side view of mytwisting apparatus. Fig. 2 is a detail view. Fig. 3 is a verticalsectional view. Fig. 4 is a detail view of the same.

The object of this invention is to prepare straw and other raw materialfor binding grain -in gavels, and for other purposes where cheap bandsare required and the nature of my invention consists in applying on oneend of a crank-shaft supported by suitable bearin gs a tubular clampingdevice and one or more hooks, for the purpose of securely holding strawor other material which it is desired to twist, as will be hereinaftermore fully explained.

In the annexed drawing, A designates a shaft, which is supported bybearings G and provided with a hand-crank on one end. On the oppositeend of this shaft A three hooks, b b b, are secured, the shanks of whichare inclosed by a tubular holder, 13, which is free to turn with, butnot around, the said shaft. Through one side of the tubular holder B istapped a thumb-screw, G, the inner end of which bears on a plate, 0.

Straw and other pliant material to be twisted is attached to one of thehooks b, and the twist is given by turning the crank-shaft.

If two or more different kinds of material are to be twisted in onestrand, the three hooks afford attachments for the material.

When the material to be twisted is either too short or too stiff forattachment to the hooks, it is inserted into the tubular holder B, andfirmly confined therein by means of the screw 0.

The twisted material should have rings or a wrapping applied on its endsto prevent untwisting when it is detached from the twisting-hooks.

WVhat I claim as new, and desire to secure by Letters Patent, is-

The hooks b, tubular holder B, and clampscrew 0, applied on acrank-shaft, A, as and for the purposes set forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

SOL KUH.
